can anyone tell me what i can expect from putting a smaller front sprocket on my monster 1100? what do i do about speedometer calibration? by the way the speedometer seems to be about 8 percent off at 65 MPH even with stock sprocket. anyone else notice this?

the bike will pull better and be easier to ride at slow speeds...less clutch slipping.

The speedo reads off the rear wheel. No correction is necessary.

All Duc speedos have been optimistic by roughly 10%.....forever. Don't know why.

There are two drawbacks, both minor. You'll lose some top end speed and the front sprocket may wear a little more than a 15T. To counter the  wear, it's better to increase the rear sprocket by 3 teeth.
